JOHN P. LEIN, OF NEW YORK, N. Y.

MATTRESS-FRAME.

SPECIFIGATIOIT forming part of Letters Patent No. 613,378, dated November 1, 1898.

I Application filed September 13, 1897. Serial No. 651,434. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN P. LEIN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Mattress-Frame, of which the following is a clear and full description.

My invention relates to mattresses, and particularly to the frames therefor.

The object of the invention is to construct a frame which shall be strong and compact and in which the hollows or open surfaces exposed to the accumulation of dust and vermin will be reduced to a minimum.

The invention will be more particularly described with reference to the forms thereof illustrated in the accompanying drawings,in which- Figure 1 is a side view of a portion of a mattress frame embodying my invention. Fig. 2 is a plan view thereof. Figs. 3 and 4 are enlarged views of details of Figs. 1 and 2, and Figs. 5, 6, 7, and 8 are modifications illustrating means for attaching the fabric to the frame proper.

In order to avoid repetition in the description of the invention, I have illustrated one corner of a frame and have described the invention with reference thereto, it being understood that the other corners are substantially the same in construction.

A represents a side rail of the mattressframe,which may be of any suitable material; but inasmuch as the invention will be found of particular value in the construction of metallic bedsteads and frames I prefer to employ tubular rails, as illustrated in the drawings, having their ends flattened and bent upward at a suitable angle and flattened. The end bars for the frame are illustrated at D. Suitable perforations O are formed in the ends of the side rails and perforations O in the end bars, whereby the rails and bars may be fastened together by a bolt E. Of course it will be understood that any suitable fastening may be used in place of the bolt here shown. Although the end bars may be of a variety of shapes or forms, I prefer the form shown in the drawings-via, an angular bar. It is to be understood, however, that I use the terms angular and angle in this specification and appended claims in their broadest sense, intending to includethereby any arch-shaped or substantially arch-shaped construction or aconstruction having two sides joined together in convenient manner, the sides lyingin difierent planes from each other. The common angle-iron of commerce is excellently adapted for my purpose, and when fastened to the side rails in the manner shown in Fig. 1that is, having the apex of the angle up and the end of the side rail fastened to the i'nneranglea most compact and strong frame is secured. The mattress-frame may be supported upon the bed by brackets or plates F, fastened to the end bars and adapted to rest upon the bed-frame, or the usual heads or platesT maybe attached to the end bar of the mattress-frame and adapted to rest in the usual chills V in the bed-frame.

J represents a clamping-piece adapted to clamp the end of the fabric to the mattressframe. In practice I prefer to locate this upon the end bars D and to use in its construction ordinary channel-iron, in order that the channel will form a convenient space to receive the edge of the fabric. The clamping-piece is clamped to the end bar by adj ustable bolts J or by any other suitable means.

In the employment of the invention the edge of the fabric to be clamped is inserted in the hollow or channel of the clampingpiece. The edge may have previously been rolled or have a rod II thrust through it, if.

preferred, and the clamping-piece is clamped upon the end bar, one edge of the clampingpiece resting directly against the end bar and the other edge clamping thefabric to the end bar. This manner of clamping will eflectually cover the rough edge of the fabric on one side of the clamping-piece byits contact with the end bar, and on the side which is in contact with the fabric paint or other'substance may be used to completely close up the opening.

Instead of clamping the fabric directly to the end bar D it may be clamped to a bar N, which is secured to the end bar by hooks K K, as shown in Fig. 5, or by spring-hooks O O, as shown in Fig.7. Likewise,in place of the square channel-iron shown in Fig. 8 a split tube D may be used, as shown in Fig. 6. Furthermore, it will be obvious that the structure here shown and described is capable of change and modification without departing from the scope or spirit of my invention, and I therefore do not limit myself herein to the construction here shown.

It will be apparent that the frame above described will be simple and inexpensive to manufacture and at the same time will possess great strength. Furthermore, only a very small amount of space is exposed to the accumulation, of dust or vermin.

Having thus described my invention, I declare that what I claim as new, and desire to secure by Letters Patent, is

1. In a mattress-frame, the combination with the fabric, of a bar to which the same is to be attached, and a channeled clampingpiece adapted to clamp the end of the fabric to said bar and cover the edge thereof, substantially as described.

2. In a mattress-frame, the combination of side rails having upwardly-turned ends, angle end bars connecting said ends, a fabric extending between said end bars, and plates carried by said end bars and adapted to engage a suitable part of the bed-frame and support the mattress-frame thereon, substantially as described.

3. In a mattress-frame, the combination of side rails having upwardly-turned flattened ends, angle end bars connecting said ends and having their angles up, a fabric engaging said end bars at their upper edges, and plates carried by said end bars and adapted to engage suitable chills on and forming part of the bed-frame, substantially as described.

4. In a mattress-frame, the combination with the fabric, of a part to which the end of said fabric is to be attached, a rod attached to the end of said fabric, and a clampingpiece adapted to clamp the fabric to said part and having a channel portion adapted to receive said rod and the edge of the fabric, substantially as described.

5. In a mattress-frame, the combination of side rails having upwardly-turned ends, angle end bars connecting said ends and having one side of the angle clamped to the ends and the other side free therefrom, a fabric, and means for attaching the fabric to the free side of the end bars, substantially as described.

6. In a mattress-frame, the combination of side rails having upwardly-turned ends, angle end bars connecting said ends and having one side of the angle clamped to the ends and the other side free therefrom, a fabric, channel-pieces, and means for clamping the ends of the fabric between the free side of the end bar and the hollow side of the channel-piece, substantially as described.

7. In a mattress-frame, the combination of side rails having upwardly-turned ends, end bars connecting said ends, a fabric extending between said end bars, a rod in the ends of said fabric, channel-pieces adapted to clamp said rods and ends of the fabric to said end bars, and means for securing said frame to a bed, substantially as described.

In testimony whereof I have hereunto set my hand this 13th day of August, 1897.
